Objective: Ventricular septal defect (VSD) is an uncommon but frequently fatal complication following acute myocardial infarction. In medically treated patients, mortality rates exceed 90%, while the surgical repair is associated with better outcomes, even though optimal surgical timing is still under debate.
Case Report: We present the case of a 78-years-old man with no previous remarkable cardiological history admitted to our Emergency Department with the diagnosis of anterior ST-elevation myocardial infarction and significant reduction of left ventricular ejection fraction. The emergency coronary angiography showed sub-occlusion of the left anterior descending coronary artery, treated with stent implantation. The post-procedural echocardiography unveiled the presence of an apical VSD with a large left-to-right shunt, significant right ventricular overload and dysfunction. An intra-aortic balloon pump (IABP) was positioned and, after Heart Team evaluation, a delayed surgical approach was planned. As a bridge to the intervention Levosimendan infusion was administered, on top of IABP support, and a significant improvement in bi-ventricular function and pressure profiles was obtained. Cardiac surgery was successfully performed 9 days after the admission without periprocedural complications.
Conclusions: This unique case supports the use of Levosimendan as a valid pharmacological strategy for perioperative management of VSD.

Incidence and Prognosis of Surgical Heart Block in Patients with L-transposition of the Great Arteries.

L-transposition of the great arteries (L-TGA) represents a spectrum of congenital heart defects (CHD) associated with atrioventricular block (AVB). However, the incidence and prognosis of postoperative AVB among patients with variants of L-TGA is uncertain. Assess the incidence and risk factors for postoperative AVB requiring permanent pacemaker (PPM) implantation for pediatric patients with L-TGA undergoing cardiac surgery.

The Berlin Heart EXCOR is a pulsatile paracorporeal ventricular assist device (VAD) for neonates, infants, children and adults with congenital or acquired severe ventricular dysfunction. Berlin Heart EXCOR VADs are routinely used as either a bridge to a cardiac transplantation, or occasionally as a bridge to ventricular recovery. Our programmatic philosophy is to bridge neonates and infants with functionally univentricular ductal-dependent systemic circulation or functionally univentricular ductal-dependent pulmonary circulation who are at high risk for staged palliation because of important cardiac risk factors with a single-ventricle VAD (sVAD) as a bridge to a cardiac transplant.

Background: Limited study has shown whether NT-proBNP is related to the prognosis of children wth ventricular septal defect (VSD) surgery. The study was conducted to determine the predictive value of NT-proBNP on outcomes of children with VSD surgery.
Methods: A total of 798 children with VSD surgery were enrolled, with NT-proBNP measured at preoperatively and 24-h postoperatively.

Masquerading bundle branch block (MBBB) is a rare presentation of bifascicular blocks. It is the result of a right bundle branch block associated with an advanced left anterior fascicular block due to extensive damage to the conduction system. We present the case of a 75-year-old male with late onset presentation anterior wall myocardial infarction (MI) with ongoing ischemia (which evolved into a ventricular septal defect [VSD]).

Aims: This retrospective cohort study aimed to investigate the efficacy of dual-chamber left Bundle branch pacing (LBBP) as an alternative therapy for heart failure patients with complete left bundle branch block (CLBBB) and indications for defibrillator with cardiac resynchronization therapy (CRT-D).
Methods: 34 patients met inclusion criteria were enrolled in the study. These criteria included a left ventricular ejection fraction (LVEF) of lower than 35%, a New York Heart Association functional class of II-IV, CLBBB meeting Strauss's criteria, intraventricular dyssynchrony, and confirmed correction of CLBBB during LBBP.
